Description
Technical field
The utility model relates to the pipeline field, and specifically a kind of straight bamboo bar that is applied in the anticorrosion occasion of agricultural irrigation, water supply and sewage work and petrochemical industry strengthens bamboo and manages again.
Background technique
In water supply and sewage work and the anticorrosion occasion of petrochemical industry, used pipeline generally adopts polyvinyl chloride pipe, polyethylene pipe, Glass Steel Tube, glass reinforced plastic sand pipe etc. at present.Polyvinyl chloride pipe and polyethylene pipe light weight, smooth and corrosion-resistant, but deficiency and raw material are the composite of petroleum products to some extent rigidity and intensity aspect; Advantage corrosion-resistant, that intensity is high, fluid resistance is little, rigidity is big that Glass Steel Tube and glass reinforced plastic sand pipe have, but the reinforcing material of product is the glass fibre of high energy consumption, its used resin oil that places one's entire reliance upon, product and waste material are not recyclable, not environmental protection.Therefore use above-mentioned duct products, consumed the petroleum resources of a large amount of preciousnesses and caused environmental pollution.For this reason, a kind of bamboo-plastic combined pipe (be called for short bamboo manage again) occurred, but the multiple tubular axis of existing bamboo is to weak strength, bending resistance, shear behavior are poor, can not be fit to use occasion such as exposing or built on stilts.
The model utility content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of straight bamboo bar to strengthen bamboo and manages again, and it makes it have excellent axial strength under the prerequisite of proof strength and rigidity.
For this reason, the utility model adopts following technological scheme: straight bamboo bar strengthens bamboo and manages again, the multiple pipe of bamboo is along the caliber direction, be followed successively by inside liner from inside to outside, enhancement layer and external protection coating, inside liner, enhancement layer and external protection coating are bonded as one by binder, it is characterized in that described enhancement layer comprises interior hoop enhancement layer, the outer axial enhancement layer and the outer hoop enhancement layer that is positioned at outermost of hoop enhancement layer in being laid on, in, outer hoop enhancement layer is entwined by many more than one deck continuous bamboo chip hoops, described axial enhancement layer is the above straight bamboo bar of curtain shape of one deck, and the straight bamboo bar in the straight bamboo bar of curtain shape axially is provided with.
The product that the utility model obtains is compared with polyvinyl chloride pipe, polyethylene pipe, has higher intensity, rigidity, has saved petroleum resources; Compare with Glass Steel Tube and glass reinforced plastic sand pipe, have similar strength and stiffness, it is lighter to compare matter, and cost is lower; Compare to the multiple pipe of the bamboo of twining or spiral twines with simple ring, possess excellent axial strength.
Above-mentioned straight bamboo bar strengthens bamboo and manages again, the length of the straight bamboo bar of curtain shape is at 0.3-3 rice, decide according to the pipeline inner diameter is different, the shortlyest be pipe one times of inner diameter, the outer perimeter of the multiple pipe of the width of the straight bamboo bar of curtain shape and bamboo matches, the straight bamboo bar of curtain shape is managed bamboo fully again coat, make the axial strength of the multiple pipe of bamboo excellent and consistent, according to the different bores of pipeline and the number of plies of usage requirement selection laying.
Above-mentioned straight bamboo bar strengthens bamboo manages again, according to the different pressure rating of pipeline, rigidity requirement, axial strength requirement, can lay the combination layer of a plurality of " axially enhancement layer (being the straight bamboo bar of curtain shape)+interior hoop enhancement layers ".
The utility model adopts continuous bamboo chip and straight bamboo bar as reinforcing material, and non-glass fiber or carbon fiber etc., environmental protection and cost are low; Owing to adopted straight bamboo bar axially to strengthen in the enhancement layer, can make pipeline possess good axial bending resistance, shear behavior, occasion such as be particularly suitable for exposing or built on stilts and use.
Below in conjunction with specification drawings and specific embodiments the utility model is elaborated.
